  • 0

I added textfield and a button in velocity script that is used through a web app. When web app is launched start.properties file is read. There’s a property: debug_on that can take two values 0 or 1.

So I want to display textfield and the button according to debug_on value. It can be done in velocity script via javascript, if I’m not mistaken (I’m not a pro in JavaScript), but I need to get the property value in order to move further.

How can I achieve it?

Velocity script example where main GWT (Java) code is embedded at the end:

<!--doctype head declaration-->

   <head>
      <meta http-equiv="content-type" content="text/html; charset=UTF-8">
      <title>Web App</title>
      <style>
        <!-- styles -->
      </style>
      <link rel="stylesheet" href="/css/webapp.css" type="text/css"/>
      <meta name='gwt:module' content='$uri'>
    </head>
    <body>
        <script language="javascript" src="/$uri/com.myproject.gwt.main.nocache.js"></script>
        <!-- TextField and button are located here -->
        <table style="width: 300px; height: 100px;" class="gwt-DialogBox" cellpadding="0" cellspacing="5">
            <!-- some other part of a page tha will be persistent through all GWT pages -->
         </table>
    </body>
    </html>

    Velocity runs on the server, JavaScript runs on the client and will not have access to any of the server’s files.

    You can use Velocity to set values within a JavaScript block and have a JS function use those values.

    <script type='text/javascript'>
var startValue = '$debug.value';
</script>
